By using lasers to treat graphene, Iowa State University researchers have found new ways to enable flexible, wearable, and low-cost electronics. Fabricating inkjet-printed, multi-layer graphene electric circuits and electrodes with a pulsed-laser process improves electrical conductivity without damaging paper, polymers, or other fragile printing surfaces.

Many things in the natural world are geometrically chiral, meaning they cannot be superimposed onto their mirror image. Being able to observe and analyze the chirality of an object is very important in numerous fields. However, current chiral imaging techniques to resolve polarization and spectral (color) information require multiple cascading components, leading to bulky and expensive pieces of equipment.

A knee band from the Georgia Institute of Technology uses microphones and vibration sensors to listen to and measure the sounds inside the joint. The sounds will help doctors determine whether a convalescing joint is healthy or requires more therapy.

An international team of researchers from the University of Illinois at Chicago and Korea University say that they have developed an ultrathin film that is both transparent and highly conductive to electric current, while also being cheaper and simpler to produce than current materials.

Researchers from Biomedical Image Technologies (BIT) at Universidad Politécnica de Madrid (UPM) are working to develop an endoscopic scanner that offers early detection of specific cancers. A miniaturized detector is introduced inside the patient's body and placed close to the organ of interest.

A team of engineers at North Carolina State University has developed an integrated, wearable system called the Health and Environmental Tracker (HET), that, they say, can monitor a user’s environment, heart rate, and other variables to predict and prevent asthma attacks. They plan to begin testing the system on a larger subject population this summer.

The Diabetes Technology Society recently announced its new cybersecurity standard for interconnected diabetes devices called DTSec. The standard specifies performance requirements utilizing the ISO/IEC 15408 framework used to define security requirements on “smart” medical devices. DTSec is initially targeted for networked devices, such as continuous glucose monitors and wireless insulin pumps, but, the group says there is nothing inherent in it to preclude its application to any other medical product or component.

Engineers at Arizona State University (ASU), Tempe, have created an edible supercapacitor that, they say, can wipe out E. coli or power a camera from inside the body. Using edible foodstuffs like activated charcoal, gold leaf, seaweed, egg white, cheese, gelatin, and barbecue sauce, which can store and conduct electricity, and sandwiching them together, the researchers created supercapacitors that can store electrical energy temporarily.

Millions of Americans at risk for blood clots, strokes, and hypertension must endure routine lab tests to monitor their blood-thinning medications, which can be frequent, costly, and painful. Now, researchers at the University of Cincinnati say that they are developing materials and technology for a simple in-home screening that could be life changing for these patients.

A non-invasive blood glucose monitor from Cardiff University's School of Engineering does not require the extraction of blood. The device, which attaches to the body via sticky adhesives, uses microwaves to measure glucose levels, sending the resulting data to a computer or mobile app.
